Description

Die Erfindung betrifft einen Glimmlampeneinsatz für elektrische Installationsschalter der im Oberbegriff des Anspruches 1 genannten Art.The invention relates to a glow lamp insert for electrical installation switches of the type mentioned in the preamble of claim 1.

Aus der DE-B-14 40 776 ist ein Glimmlampeneinsatz bekannt, der zwei am Sockelaufbau des Glimmlampeneinsatzes befestigte Kontaktfedern besitzt, welche für eine unmittelbare Kontaktierung mit Kontaktteilen des Schalters vorgesehen sind. Zusätzlich ist am Sockel eine Schraubklemme vorgesehen, an der unabhängig vom Schalter ein Leitungsdraht befestigt werden kann. Die Glimmlampe liegt mit einem Vorwiderstand zwischen der Schraubklemme und einer der beiden Kontaktfedern. Der Glimmlampeneinsatz kann je nach Anschlußart zwei unterschiedliche Funktionen erfüllen.

  • (1) Zum einen soll die Glimmlampe vorrangig zur Pilotbeleuchtung einer Schalter-Taste dienen. (Schaltfolge: Schalter aus/Lampe brennt bzw. Schalter ein/Lampe brennt nicht).
  • (2) Zum anderen soll die Glimmlampe vorrangig zur Kontrolle einer Schalter-Ausschaltung dienen. (Schaltfolge: Schalter aus/Lampe brennt nicht bzw. Schalter ein/Lampe brennt)
From DE-B-14 40 776 a glow lamp insert is known which has two contact springs attached to the base structure of the glow lamp insert, which are provided for direct contact with contact parts of the switch. In addition, a screw terminal is provided on the base, to which a lead wire can be attached independently of the switch. The glow lamp is located with a series resistor between the screw terminal and one of the two contact springs. The glow lamp insert can perform two different functions depending on the type of connection.
  • (1) On the one hand, the glow lamp should serve primarily for pilot lighting of a switch button. (Switching sequence: switch off / lamp burns or switch on / lamp does not burn).
  • (2) On the other hand, the glow lamp should primarily serve to control a switch opening. (Switching sequence: switch off / lamp does not burn or switch on / lamp burns)

Die Funktion (1) wird dadurch erreicht, daß der Abgriff für die Stromversorgung der Glimmlampe über die beiden Kontaktfedern parallel zum Schalter erfolgt. Hierbei muß eine an der Anschlußklemme befestigte Kontaktbrücke den elektrischen Kontakt zwischen der Schraubklemme und einem Kontaktteil des Schalters herstellen.Function (1) is achieved in that the tap for the power supply of the glow lamp is made via the two contact springs parallel to the switch. Here, a contact bridge attached to the connection terminal must establish the electrical contact between the screw terminal and a contact part of the switch.

Die Funktion (2) wird dadurch gewährleistet, daß der Glimmlampeneinsatz ohne die Kontaktbrücke verwendet wird. Die Glimmlampe steht dabei mit nur einer Kontaktfeder in Verbindung. Den zweiten Pol bildet die Schraubklemme, an die der Null-Leiter angeschlossen wird.Function (2) is ensured by using the glow lamp insert without the contact bridge. The glow lamp is connected to only one contact spring. The second pole is the screw terminal to which the neutral conductor is connected.

Nachteilig ist bei diesem bekannten Glimmlampeneinsatz, daß eine Schraubklemme verwendet wird, die drei unterschiedliche Anschlußmöglichkeiten für die Zuleitung der Glimmlampe, den Anschluß des Leitungsdrahtes zur Verbindung mit dem Nulleiter und die als Kontaktzunge ausgebildete Kontaktbrücke zur Kontaktierung eines Kontaktteils des Schalters, benötigt. Die Schraubklemme ist dadurch relativ kompliziert aufgebaut und erfordert entsprechende Maßnahmen zu ihrer Befestigung in oder an dem Glimmlampengehäuse.The disadvantage of this known glow lamp insert is that a screw terminal is used which requires three different connection options for the supply of the glow lamp, the connection of the lead wire for connection to the neutral conductor and the contact bridge designed as a contact tongue for contacting a contact part of the switch. As a result, the screw terminal is of relatively complicated construction and requires corresponding measures for fastening it in or on the glow lamp housing.

Weiterhin ist aus der DE-A-16 90 400 ein zweiteiliger Glimmlampensockel bekannt, der am Sockeloberteil eines Installationsgerätes aufgesteckt werden kann, wobei im Sockeloberteil untergebrachte schraubenlose Anschlußklemmen zur Stromversorgung der Glimmlampe kontaktiert werden. Die mit einer Klemmfeder versehene Anschlußklemme ist somit in bekannter Weise dem Installationsgerät zugeordnet und an dem Glimmlampensockel wurden keine Maßnahmen getroffen, die eine wahlweise Verwendung des gleichen Sockels der Glimmlampe und des Installationsgerätes einerseits als Pilotleuchte und andererseits als Kontrolleuchte ermöglichen.Furthermore, from DE-A-16 90 400 a two-part glow lamp base is known, which can be plugged onto the upper part of an installation device, contact being made in the upper part of the screwless connection terminals for supplying power to the glow lamp. The terminal provided with a clamping spring is thus assigned to the installation device in a known manner, and no measures have been taken on the glow lamp base that enable the same base of the glow lamp and the installation device to be used on the one hand as a pilot light and on the other hand as a control light.

Aufgabe der Erfindung ist es, Aufbau und Montage eines Glimmlampeneinsatzes nach dem Oberbegriff des Anspruches 1 zu vereinfachen. Außerdem soll das Kontaktieren der verschiedenen mit der Anschlußklemme zu verbindenden Leiter erleichtert werden.The object of the invention is to simplify the construction and assembly of a glow lamp insert according to the preamble of claim 1. In addition, the contacting of the various conductors to be connected to the connection terminal is to be facilitated.

Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 gekennzeichneten Merkmale gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the features characterized in claim 1. Advantageous refinements and developments of the invention are characterized in the subclaims.

Der erfindungsgemäße Glimmlampeneinsatz besitzt eine in eine mit der Glimmlampe in elektrischem Kontakt stehende Anschlußklemme eingeklemmte zweite Kontaktfeder, welche zwecks Kontaktierung mit einem Schalterkontaktteil eine Kontaktfahne aufweist. Die zweite Kontaktfeder ist hierbei nicht fest auf dem Glimmlampensockel installiert, sondern lösbar in der Anschlußklemme eingeklemmt.The glow lamp insert according to the invention has a second contact spring which is clamped in a terminal which is in electrical contact with the glow lamp and which has a contact lug for the purpose of contacting a switch contact part. The second contact spring is not permanently installed on the glow lamp base, but is releasably clamped in the connection terminal.

Die Anschlußklemme ist nicht als Schraubklemme, sondern als Federklemme ausgeführt, was eine weitere Vereinfachung bedeutet. Der Kontaktschluß wird durch den Federanpreßdruck der im Klemmstück auf Spannung gehaltenen Blattfeder genausogut gewährleistet, wie im Falle eines Anpreßdruckes, der durch das Anziehen einer Schraube aufgebaut wird. Vorteilhaf ist, daß auch die zweite Zuführungsleitung der Glimmlampe schnell und einfach in die Federklemme eingeklemmt werden kann. Das gleiche gilt für den ggf. anzuschließenden Leitungsdraht.The connection terminal is not designed as a screw terminal, but as a spring terminal, which means a further simplification. The contact closure is ensured by the spring contact pressure of the leaf spring held in tension in the clamping piece as well as in the case of a contact pressure which is built up by tightening a screw. It is advantageous that the second supply line of the glow lamp can also be quickly and easily clamped into the spring clip. The same applies to the line wire to be connected if necessary.

Gemäß einem vorteilhaften Ausführungsbeispiel ist die Kontaktfahne der zweiten Kontaktfeder an einem S-förmig gebogenen mittleren Teilbereich der zweiten Kontaktfeder endseitig angebracht. Hierdurch kann ein frontaler Anpreßdruck zwischen der zweiten Kontaktfeder und einem Schalterkontaktteil aufgebaut werden, sobald der Glimmlampeneinsatz in den Schaltersockel eingesetzt wird. Dadurch kann der Aufbau eines ausreichenden lateralen Kontaktdruckes, wie er bei der zweiten Kontaktfeder des bekannten Glimmlampeneinsatzes nur mittels doppelt gelegter und aufgespreizter Kontaktfedern erreicht werden kann, entfallen.According to an advantageous embodiment, the contact lug of the second contact spring is attached at the end to an S-shaped middle section of the second contact spring. As a result, a frontal contact pressure can be built up between the second contact spring and a switch contact part as soon as the glow lamp insert is inserted into the switch base. As a result, the build-up of a sufficient lateral contact pressure, as can only be achieved with the second contact spring of the known glow lamp insert, by means of double-laid and spread contact springs, can be dispensed with.

Ist die zweite Kontaktfeder in die Federklemme eingesetzt, kann der Glimmlampeneinsatz für Beleuchtungszwecke Verwendung finden. Die Stromversorgung der Glimmlampe erfolgt zum einen über die erste Kontaktfeder sowie zum anderen mittelbar über die zweite Kontaktfeder zur Anschlußklemme der Glimmlampe. (Schaltfolge: Schalter aus/Lampe brennt bzw. Schalter ein/Lampe brennt nicht).If the second contact spring is inserted in the spring clip, the glow lamp insert can be used for lighting purposes. The glow lamp is powered on the one hand via the first contact spring and on the other hand indirectly via the second contact spring to the connection terminal of the glow lamp. (Switching sequence: switch off / lamp burns or switch on / lamp does not burn).

Soll der Glimmlampeneinsatz für Zwecke der Ausschaltungs-Kontrolle Anwendung finden, kann die zweite Kontaktfeder leicht entfernt werden. Der in diesem Fall erforderliche Leitungsdraht, ein Null-Leiter, kann dann ebenso leicht in die als Federklemme ausgestaltete Anschlußklemme eingeklemmt werden. (Schaltfolge: Schalter ein/Lampe brennt bzw. Schalter aus/Lampe brennt nicht).If the glow lamp insert is to be used for the purpose of switching off control, the second contact spring can be easily removed. The lead wire required in this case, a neutral conductor, can then just as easily be clamped into the connection terminal designed as a spring terminal. (Switching sequence: switch on / lamp burns or switch off / lamp does not burn).

Anhand der Zeichnung, in der zwei Ausführungsbeispiele der Erfindung dargestellt sind, soll die Erfindung beschrieben und näher erläutert werden.The invention is to be described and explained in more detail with reference to the drawing, in which two exemplary embodiments of the invention are shown.

Die Figuren 1 bis 6 zeigen einen Glimmlampeneinsatz des ersten Ausführungsbeispiels, der im Boden des Schaltersockels befestigbar ist; die Figuren 7 bis 12 zeigen einen Glimmlampeneinsatz des zweiten Ausführungsbeispiels, der auf der Oberseite des Schaltersockels, seitlich vom Schalterbetätigungselement, befestigbar ist.Figures 1 to 6 show a glow lamp insert of the first embodiment, which can be fastened in the bottom of the switch base; Figures 7 to 12 show a glow lamp insert of the second embodiment, which can be attached to the top of the switch base, to the side of the switch actuating element.

Gemäß dem in den Figuren 1 bis 6 dargestellten ersten Ausführungsbeispiel besteht der Glimmlampeneinsatz im wesentlichen aus einem Oberteil 1 und einem Unterteil 2 eines Glimmlampengehäuses, welches durch erste und zweite eine Rastverbindung bildende Rastnasen 13, 14 Zusammengehalten wird, einer Glimmlampe 3, einem der Strombegrenzung dienenden Vorwiderstand 4, einer in einem Fach des Oberteils 1 des Glimmlampengehäuses angeordneten Anschlußklemme 6, einer ersten Kontaktfeder 5 und einer zweiten Kontaktfeder 7, sowie einer ersten und einer zweiten Zuführungsleitung 8, 9. Erste Kontaktfeder 5, erste Zuführungsleitung 8, Vorwiderstand 4, Glimmlampe 3, zweite Zuführungsleitung 9 sowie zweite Kontaktfeder 7 sind in dieser Reihenfolge elektrisch in Reihe geschaltet.According to the first exemplary embodiment shown in FIGS. 1 to 6, the glow lamp insert essentially consists of an upper part 1 and a lower part 2 of a glow lamp housing, which is held together by first and second latching lugs 13, 14 forming a latching connection, a glow lamp 3, one which serves to limit the current Series resistor 4, a terminal 6 arranged in a compartment of the upper part 1 of the glow lamp housing, a first contact spring 5 and a second contact spring 7, and first and second supply lines 8, 9. First contact spring 5, first supply line 8, series resistor 4, glow lamp 3 , second supply line 9 and second contact spring 7 are electrically connected in series in this order.

Die als Federklemme ausgebildete Anschlußklemme 6 besteht aus einem Klemmstück 10 und einer Blattfeder 11. Das Klemmstück 10 besteht vorzugsweise aus einem U-förmigen Metallstück, an dessen einer Wandung eine V-förmige Rille 30 eingeformt ist. Diese Rille 30 dient der klemmfesten Aufnahme eines Leitungsdrahtes 21. Die Blattfeder 11 besteht aus einem im wesentlichen V-förmig gebogenen Stück Bandmetall. Aufgrund der an der gebogenen Blattfeder 11 auftretenden Druckspannung wird sowohl die zweite Zuführungsleitung 9 als auch die zweite Kontaktfeder 7 gegen eine Wandung des Klemmstückes 10 gepreßt und festgehalten. Weiter wird dadurch, daß der eine Klemmschenkel der Blattfeder 11 einen spitzen Winkel, vorzugsweise 45°, mit dem einen Ende der zweiten Kontaktfeder 7 bildet, sowie dadurch, daß der eine Schenkel scharfrandig in die zweite Kontaktfeder 7 eingreift, ein Herausrutschen der zweiten Kontaktfeder 7 weitgehend verhindert. Sofern man mit einem geeigneten Werkzeug (z.B. einem Schraubendreher) durch zwei sich überlappende, sowohl in Oberteil 1 als auch im Unterteil 2 des Glimmlampengehäuses angebrachte Durchbrüche 15 hindurchgreift und die Blattfeder 11 gegen die vorliegende Spannung zusammendrückt, läßt sich die zweite Kontaktfeder 7 herausschieben. Auf dem gleichen Weg läßt sich der Leitungsdraht 21 einschieben und festklemmen. Da die Anschlußklemme 6 als Federklemme ausgebildet ist, läßt sich in einfacher und zweckmäßiger Weise auch ein Ende der zweiten Zuführungsleitung 9 zwischen Klemmstück 10 und Blattfeder 11 der Anschlußklemme 6 einklemmen, wie insbesondere Figur 4 zeigt. Die zweite Kontaktfeder 7 ist im mittleren Bereich zum Zwecke des Aufbaues einer Federdruckkraft S-förmig gebogen und somit federnd elastisch ausgebildet. Die Kontaktfahne 12 der zweiten Kontaktfeder 7 wird durch das eine Ende der zweiten Kontaktfeder 7 gebildet, welches aus dem Oberteil 1 des Glimmlampengehäuses herausragt.The terminal 6 designed as a spring clip consists of a clamping piece 10 and a leaf spring 11. The clamping piece 10 preferably consists of a U-shaped metal piece, on the wall of which a V-shaped groove 30 is formed. This groove 30 is used to hold a lead wire 21 in a non-jamming manner. The leaf spring 11 consists of an essentially V-shaped piece of strip metal. Because of the compressive stress occurring on the bent leaf spring 11, both the second feed line 9 and the second contact spring 7 are pressed against a wall of the clamping piece 10 and held. Furthermore, the fact that the one clamping leg of the leaf spring 11 forms an acute angle, preferably 45 °, with one end of the second contact spring 7, and because one leg engages in the second contact spring 7 with sharp edges, prevents the second contact spring 7 from slipping out largely prevented. If one reaches with a suitable tool (e.g. a screwdriver) through two overlapping openings 15, both in upper part 1 and in lower part 2 of the glow lamp housing, and compresses the leaf spring 11 against the existing tension, the second contact spring 7 can be pushed out. In the same way, the lead wire 21 can be inserted and clamped. Since the connecting terminal 6 is designed as a spring terminal, one end of the second supply line 9 can also be clamped between the clamping piece 10 and the leaf spring 11 of the connecting terminal 6 in a simple and expedient manner, as shown in particular in FIG. The second contact spring 7 is bent in an S-shaped manner in the central region for the purpose of building up a spring pressure force and is thus of resiliently elastic design. The contact tab 12 of the second contact spring 7 is formed by one end of the second contact spring 7, which protrudes from the upper part 1 of the glow lamp housing.

Wenn die am Oberteil 1 des Glimmlampengehäuses angeformte Hülse 19 zum Zwecke der zuverlässigen Halterung des Glimmlampeneinsatzes am Schaltersockel 17 in die entsprechende Sockelaufnahme 18 des Schaltersockels 17 eingeführt und mittels dritter Rastnasen 20 verrastend gehalten wird, drückt sich die entsprechend dimensionierte zweite Kontaktfeder 7 etwas zusammen, wodurch sie mit einem gewissen Kontaktdruck das Kontaktteil 16 des Schalters kontaktiert.If the sleeve 19 molded onto the upper part 1 of the glow lamp housing is inserted into the corresponding base receptacle 18 of the switch base 17 for the purpose of reliably holding the glow lamp insert on the switch base 17 and held in a latching manner by means of third latching lugs 20, the correspondingly dimensioned presses second contact spring 7 together somewhat, whereby it contacts the contact part 16 of the switch with a certain contact pressure.

Die Figuren 7 bis 12 zeigen den Glimmlampeneinsatz des zweiten Ausführungsbeispiels.
